STM32 External Interrupt Controller Required properties: - compatible: Should be: "st,stm32-exti" "st,stm32h7-exti" "st,stm32mp1-exti" - reg: Specifies base physical address and size of the registers - interrupt-controller: Indentifies the node as an interrupt controller - #interrupt-cells: Specifies the number of cells to encode an interrupt specifier, shall be 2 - interrupts: interrupts references to primary interrupt controller (only needed for exti controller with multiple exti under same parent interrupt: st,stm32-exti and st,stm32h7-exti) Optional properties: - hwlocks: reference to a phandle of a hardware spinlock provider node. Example: exti: interrupt-controller@40013c00 { compatible = "st,stm32-exti"; interrupt-controller; #interrupt-cells = <2>; reg = <0x40013C00 0x400>; interrupts = <1>, <2>, <3>, <6>, <7>, <8>, <9>, <10>, <23>, <40>, <41>, <42>, <62>, <76>; };
